如果R遇到错误，如何使R发送警报？ [英] How can I make R send an alert if it encounters an error?

问题描述

由于 mail 软件包，我目前喜欢在R脚本运行完毕后收到电子邮件通知。

I currently enjoy receiving email notifications when my R scripts have finished running, thanks to the mail package.

但是，我想知道是否有可能让R（或RStudio或其他东西）通知我，如果脚本因为遇到脚本失败而无法完成运行错误？电子邮件将是最好的传递方法。

However, I would like to know if it's possible to have R (or RStudio, or something else) notify me if a script fails to finish running because it has encountered an error? Email would be the best delivery method.

当我在远程计算机上运行代码或不在计算机上时，这将非常有用。 / p>

This would be extremely useful when I'm running code on a remote machine, or when I'm away from my computer.

推荐答案

获取推送消息： http://cran.r-project.org/web/packages/RPushbullet/index.html

或给自己发送电子邮件： http://cran.r-project.org/ web / packages / mailR /

Or send yourself an email: http://cran.r-project.org/web/packages/mailR/

并使用tryCatch ...

And use tryCatch...

a <- tryCatch({
    source("your_script.R")
}, warning = function(w) {
    warning-handler-code
}, error = function(e) {
    send mail, pushbullet, etc...
}, finally = {
    cleanup
}
